[NTG-context] Bug? setupinteraction makes footnotenumber bold

For having the bookmarks when viewing my PDF in Acrobat I use \setupinteraction[state=start] But this forces the footnotenumbers (both in the text and in the footer) to be bold. Is this a known bug? Here a minimal example: %\setupinteraction[state=start] \setupfootnotes[style=italic] \starttext Test Test.\footnote{Fussnotentext} \stoptext With the first line to be (un-)commented. Steffen
